https://devzone.nordicsemi.com/f/nordic-q-a/44613/nrf9160-sip-sd-card-interfaceHi, Is it possible to add SD card (either SPI or MMC mode) to nRF9160-SiP? Hoping since the SiP is powered by Zephyr-OS, that should be possible. Please advise. Thanks in advance, for your attention and any help.en-USTelligent Community 13Fri, 08 Mar 2019 23:40:32 GMThttps://devzone.nordicsemi.com/thread/175156?ContentTypeID=1Fri, 08 Mar 2019 23:40:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5751cd49-5901-4f83-ae6d-4d8403314f6fMartin<p>The nRF9160 has no QSPI interface but you can use a SPI interface and connect CLK, CS, MOSI, MISO to CLK, D3, CMD, D0.&nbsp;<br />D1 and D2 from the SDcard are not connected and should probably pulled-up.<br />Please note that you probably need at least 2.8V for power and IO.</p><div style="clear:both;"></div>
